Analysis: It is expected that the difficulty of mining Bitcoin will be adjusted upwards, and the profitability index of miners, hashprice, has fallen to a freezing level. News from ChainCatcher, according to a report by Cointelegraph, the difficulty of the Bitcoin network is expected to increase from about 149.3 million trillion to about 149.8 million trillion in the next adjustment, meaning that mining competition will become even fiercer. Meanwhile, the key indicator to measure the profitability of miners, hashprice, has dropped to near record lows - daily profits of about 38.3 dollars per PH/s, lower than the breakeven level for most miners. Industry analyses indicate that such a combination (increased difficulty + dismal hashprice) will further squeeze the profit margins of miners; smaller miners or those with high electricity bills may be forced to shut down, and the industry may accelerate restructuring.
